Description

Technical Field

[0001] This utility model belongs to the field of metallurgy, and in particular relates to a cooling mold for the production of metallic silicon. Background Technology

[0002] Silicon metal is an important industrial raw material widely used in electronics, chemicals, metallurgy, and other industries. With the rapid development of these industries, the requirements for the quality and yield of silicon metal are constantly increasing. Therefore, developing efficient and reliable silicon metal production technologies and equipment is of significant practical importance. Cooling molds, as one of the key pieces of equipment in the silicon metal production process, directly affect the quality and production efficiency of the silicon metal.

[0003] Existing equipment often results in silicon metal getting stuck in the mold during demolding, making it difficult to remove and causing instability in the demolding process. Using other tools to remove the silicon metal from the mold can damage the inner wall of the mold, reducing its lifespan. Furthermore, if the mold is not cleaned after demolding, new silicon metal can be mixed with other impurities, leading to uneven composition. Residual impurities in the mold can also cause demolding difficulties and increase the friction between the silicon metal and the mold. Therefore, we propose a cooling mold for silicon metal production. Utility Model Content

[0004] The purpose of this invention is to provide a cooling mold for the production of metallic silicon. By using a top block and a scraper, it solves the problems of metallic silicon getting stuck in the mold during demolding, making it difficult to remove and causing instability in the demolding process. It also addresses the issues of other tools damaging the inner wall of the mold and reducing its service life when used to remove the metallic silicon, and the possibility of new metallic silicon being mixed with other impurities after demolding if the mold is not cleaned, resulting in uneven composition. Furthermore, residual impurities in the mold can cause demolding difficulties and increase the friction between the metallic silicon and the mold.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a cooling mold for the production of metallic silicon, comprising several support legs. The top of each support leg is fixedly connected to a mold, and the bottom of the mold is fixedly connected to a water pipe. Support frames are fixedly connected to the outer walls of the support legs. A circular groove is formed on the inner wall of the mold. A demolding mechanism is provided at the bottom of the mold. The demolding mechanism includes a fixed frame, which is fixedly connected to the mold. A rotating shaft is rotatably connected to the inner wall of the fixed frame. A cleaning mechanism is provided on the outer wall of the mold. The cleaning mechanism includes a fixed block, which is fixedly connected to the mold. A sliding plate is fixedly connected to the inner wall of the fixed block.

[0007] The above technical solution involves storing metallic silicon in a mold, allowing the molten metallic silicon to solidify and take shape inside the mold.

[0008] Furthermore, a worm gear is rotatably connected to the inner wall of the support frame, and a turntable is fixedly connected to the outer wall of the worm gear near the fixed frame.

[0009] The above technical solution uses the rotation of the turntable to drive the worm gear to rotate, which in turn drives the worm wheel to rotate.

[0010] Furthermore, a worm gear is fixedly connected to the outer wall of the rotating shaft, the worm meshes with the worm gear, and a threaded rod is fixedly connected to the outer wall of the rotating shaft on the side away from the worm gear.

[0011] The above technical solution uses the rotation of the worm gear to drive the rotating shaft to rotate, and the rotation of the rotating shaft will drive the threaded rod to rotate.

[0012] Furthermore, the outer wall of the threaded rod is threadedly connected to a threaded tube, and the outer wall of the threaded tube is fixedly connected to a top block, which is slidably connected to the circular groove.

[0013] The above technical solution allows the solidified silicon metal to be ejected from the mold by moving the top block, making material removal more convenient.

[0014] Furthermore, a rotating rod is rotatably connected to the inner wall of the turntable on the side away from the worm gear, and a plurality of sliding grooves are provided on the inner wall of the fixed block, with sliders slidably connected to the inner walls of the plurality of sliding grooves.

[0015] The above technical solution allows the column to move by moving the slider, and the slider can then maintain horizontal movement within the groove.

[0016] Furthermore, a column is fixedly connected to the top of several of the sliders, and a crossbar is fixedly connected to the top of the column.

[0017] The above technical solution allows the horizontal bar to move to different positions on the mold by moving the column.

[0018] Furthermore, the inner wall of the crossbar is provided with a number of slots, and damping rods are slidably connected to the inner walls of the slots.

[0019] By using the above technical solution, the spring is fixed by a damping rod, and the spring will not shift to the left or right when it is compressed.

[0020] Furthermore, springs are fixedly connected to the outer walls of several of the damping rods, and scrapers are fixedly connected to the bottom of the damping rods.

[0021] The above technical solution uses a scraper to clean the mold, and the residue on the surface can be cleaned after the mold is used.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model incorporates a top block. When the threaded rod rotates, it drives the threaded tube upward, which in turn moves the top block. The top block then slides within a circular groove on the mold, fitting snugly against the mold. As the top block moves, it ejects the solidified silicon metal from the mold, achieving rapid demolding. This effectively prevents the silicon metal from getting stuck in the mold, improving work efficiency, allowing for stable control of the demolding process, and avoiding damage to the inner wall of the mold during demolding, thus extending the mold's service life.

[0024] 2. This utility model incorporates a scraper. When the damping rod slides, it drives the scraper to move, and then the scraper moves to the surface of the mold. As it continues to move, the scraper cleans the surface of the mold, scraping off any residual silicon metal. The residual silicon metal is then scraped onto the sliding plate, thus cleaning the mold and preventing residual silicon metal or other impurities from mixing into the new silicon metal, which could lead to uneven product composition and impurities. At the same time, it prevents residue on the mold surface from increasing the friction between the silicon metal and the mold, making demolding difficult.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A rotating shaft 202 is rotatably connected to the inner wall of the fixing frame 201. A cleaning mechanism 3 is provided on the outer wall of the mold 101. The cleaning mechanism 3 includes a fixing block 301, which is fixedly connected to the mold 101. A sliding plate 302 is fixedly connected to the inner wall of the fixing block 301.

[0036] As shown in Figures 1-3, a worm gear 207 is rotatably connected to the inner wall of the support frame 103, and a turntable 208 is fixedly connected to the outer wall of the worm gear 207 near the fixed frame 201.

[0037] As shown in Figure 2-3, a worm gear 203 is fixedly connected to the outer wall of the rotating shaft 202, and the worm 207 meshes with the worm gear 203. A threaded rod 204 is fixedly connected to the outer wall of the rotating shaft 202 on the side away from the worm gear 203.

[0038] As shown in Figures 1-3, the outer wall of the threaded rod 204 is threadedly connected to a threaded tube 205, and the outer wall of the threaded tube 205 is fixedly connected to a top block 206, which is slidably connected to the circular groove 104.

[0039] As shown in Figure 2-5, a rotating rod 209 is rotatably connected to the inner wall of the turntable 208 on the side away from the worm gear 203. Several grooves 309 are opened on the inner wall of the fixed block 301, and sliders 303 are slidably connected to the inner walls of the grooves 309.

[0040] As shown in Figure 5, several sliders 303 are fixedly connected to the top of a column 304, and the top of the column 304 is fixedly connected to a crossbar 305.

[0041] As shown in Figures 4-5, the inner wall of the crossbar 305 has several slots 310, and the inner walls of the slots 310 are slidably connected to damping rods 306.

[0042] As shown in Figures 4-5, springs 307 are fixedly connected to the outer walls of several damping rods 306, and scrapers 308 are fixedly connected to the bottom of the damping rods 306.

[0043] One specific application of this embodiment is:

[0044] When the equipment is needed, the water pipe 102 is first connected to an external water source. Then, the molten silicon is poured into the mold 101. The presence of silicon in the mold 101 will transfer heat into it. The mold 101 will then be continuously cooled through the water pipe 102, accelerating the cooling of the silicon. After the silicon solidifies, the rotating rod 209 can be rotated. The rotation of the rotating rod 209 will drive the turntable 208 to rotate, which in turn drives the worm gear 207. The rotation of the worm gear 207 drives the worm wheel 203 to rotate, which in turn drives the rotating shaft 202 to rotate. The rotating shaft 202 then drives the threaded rod 204 to rotate, which in turn rotates within the threaded tube 205. This rotation of the threaded rod 204 causes the threaded tube 205 to move upwards, which in turn moves the ejector block 206. The ejector block 206 then slides within the circular groove 104 on the mold 101. Finally, the ejector block 206 interacts with the mold... The mold 101 is fitted, and when the top block 206 moves, it will push the solidified silicon metal out of the mold 101, making it easier to remove the silicon metal. After the silicon metal is removed, the column 304 can be pushed. When the column 304 moves, it will drive the slider 303 to move. Then the slider 303 will move in the groove 309 on the fixed block 301. At the same time, when the column 304 moves, it will drive the crossbar 305 to move. When the crossbar 305 moves, it will drive the damping rod 306 and the scraper 308 to move. When the scraper 308 moves to... When the spring 307 presses the damping rod 306 on the mold 101, the damping rod 306 slides in the slot 310 on the crossbar 305. When the damping rod 306 slides, it will drive the scraper 308 to move. Then the scraper 308 will move to the surface of the mold 101. When it continues to move, the scraper 308 will clean the surface of the mold 101, scraping off the residual metal silicon. Then the residual metal silicon will be scraped onto the slide plate 302, and then slide off the slide plate 302, and finally be collected.
